I just purchased a Porter-Cable left-blade 743K and now I keep thinking I might take it back and now I keep thinking I’m going to keep it. The problem lies here: I was thinking I wanted to get the six inch SawBoss (it’s cute, light, high rpm, and performs just fine for most construction tasks) but then I thought I should just go ahead and get the regular ol’ 7 1/4″ instead. I am right-handed and like to see my cuts when free-handing so left-blade makes sense, right? Anyhow, as I was looking through the manual I discovered that using the saw as I do is supposedly very dangerous and I thought: maybe I should have gotten the blade-right and just get used to it. Then I thought: worm-drives are pretty much only blade-left and the Skil 77 is very popular among carpenters. Carpenters can’t possibly all be left-handed so there must be a number of others out there in the world who, according to the instructions, behave without their best interests in mind. So, I should keep the blade-left model because that’s what I’m used to or I should trade it in for the blade-right model because I’m right-handed and the instructions say I’d be safer. So, the question is: does it really make much of a difference safety-wise or am I just being ridiculously anxious?
